Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.
This is the current replacement for some BMW 6 and 8-cylinder engines built in the late 2000s and after. BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed below. It's listed as a replacement coil for N20, N55, and S55 engines. In March 2015 BMW approved it for N51/N52 engines. This part number replaces the previous BMW part number 12137594937 for the cars listed below.
Sold per coil. Includes boot and connector.

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent. The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories. These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.
Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.
Fits the following BMWs:
2000-2006 E46 BMW 323/325/328/330
Before ordering, check whether you need round or flat pin connectors for your MINI's coil pack. The type of pin is determined by the connectors that link the coil to the wiring harness. To check, slide the red locking tab to the right, press down on the tab, and pull the connector off the coil. Examine the pins to see if they are flat or round. Reattach the connector by pushing it back on until it clicks, then slide the red locking tab back to the locked position.
This high-performance coil pack is a popular upgrade among MINI owners looking to enhance their vehicle's performance over the stock coil. The installation requires removing the factory bolts from the old coil and modifying the MSD factory sleeves by drilling out 1/16" to fit the stock bolts.

From the factory, all BMWs utilize soft rubber or fluid-filled engine mounts. Not only are these mounts prone to degradation, they also allow ample movement of the drivetrain. This translates to looseness in your driveline, commonly associated with missed shifts and a generally isolated feeling.
To improve upon this issue, Black Forest Industries designed these upgraded mounts from the ground up. Their stage one mounts feature a proprietary 65A durometer bushing and bracket/cup design. Maximizing bushing area while minimizing vibration gives this mount the advantage of having the best ride characteristics possible from a urethane mount.
Features:
Perfect fit: Utilizing laser-scanning technology permits seamless integration with the factory engine mount arms. Quality tooling: All bosses are matched replicas with stock locations, and all tool clearances and specs are maintained. Heavy-duty construction: The use of billet aluminum instead of cast creates a mount that is dramatically stronger than its factory cast-construction counterpart. Performance design: 65A durometer bushings are geared toward the spirited driving enthusiast who wants better control over motor movement without sacrificing excessive vibrations. Choose BFI Stage 1 for a quality mount that eliminates drivetrain movement without adding excessive NVH.
